A subdomain name (or subdomain; in Chinese: 子域) is a domain that belongs to a higher-level domain in the Domain Name System hierarchy. For example, mail.example.com and calendar.example.com are two subdomains of example.com, which is a subdomain of the top-level domain. Please visit.

However, how you use it depends on your application object. If you want to create a subdomain, first pay attention to whether your website is suitable for doing so. If you are a large website, such as 58, Ganji, Tencent, NetEase, and Sina, you will naturally choose a subdomain, because your scale has reached a certain level, and the information and resources of these websites are huge and extensive. There is nothing wrong with using a single subdomain to create content for a field and industry, and you don’t need to stick to using a single keyword, but instead consider user habits.

If you are a small to medium sized website, using subdomains is not recommended at this time. I suggest using subdirectories because subdomains are equivalent to brand new websites and will not bring you high SEO performance in the short term. In addition, the content data of your own small and medium-sized websites is relatively small and not enough to support the number of subdomains. Additionally, subdomains increase maintenance costs and workload. If you don't have enough verses to manage, your weight will cause a leveling phenomenon.
